Vorrichtung zur Bestimmung einer momentanen Durchflussrate eines fließfähigen Mediums

Disclosed is a device for determining a current flow rate of a flowable medium, said device comprising a measuring housing section for receiving measuring means, and comprising a measuring line section through which the flowable medium can flow, whereby a suspended body can be raised, a measuring section of which body protrudes into the flowable medium, wherein: the suspended body is connected to a guiding section which protrudes into the measuring housing section; a signal means, in particular a magnet means, is arranged in a holding region, in particular an end region, of the guiding section; an in particular height-adjustable position sensor for registering the movement of a signal means, in particular a magnet means, is arranged adjacently to the signal means, in particular the magnet means, on the holding region of the guiding section of the suspended body, in particular a reed contact and/or Hall effect sensor, the sensor being arranged in a substantially stationary manner in relation to the outer measuring housing section; and wherein the position sensor, in particular the reed contact and/or Hall effect sensor, can be activated as a result of a magnet means movement caused by the suspended body movement.
